LOCK.

To all whom it may concern:

Be it known that I, RAFFAELE FEoLA, a citizen of the United States, anda resident of the city of New York, borough of Manhattan, in the countyand State of New York, have invented a new and Improved Lock, of whichthe following is a full, clear, and exact description.

This invention relates to locks, and more particularly to a lock servingthe purposes of a pad-lock but having the casing so constructed that itfits closely around the staples or eyes which receive the pad-lock bolt,and fits closely against the door or other support carrying the staples,the bolt of the lock lying normally completely within the casing andhaving key-controllable means for releasing the bolt so that it can beprojected from the casing and drawn out of engagement with the staples.

The object of the invention is to provide a simple, inexpensive anddurable lock which serves the purposes of a pad-lock, which when inposition prevents the staples or eye-bolts from being filed or cut, andrenders diflicult other unauthorized methods of opening the lock.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which Figure 1 is aperspective view showing part of a double door having an embodiment ofmy invention applied thereto; Fig. 2 is a longitudinal section on theline 2-2 of Fig. 1; Fig. 3 is a similar View showing certain of theparts in different positions; Fig. 4 is a longitudinal section of thebolt, showing a key in position to release the bolt; Fig. 5 is atransverse section of part of a door and a door frame showing a lock ofmodified form; Fig. 6 is a longitudinal section on the line 66 of Fig.5; Fig. 7 is a sectional view somewhat similar to Fig. 2, and showing adifierent form of my improved lock; Fig. 8 is an enlarged view partly inplan and partly in section showing a slightly different form of lockthan that shown in Figs. 1 to 7 inclusive; Fig. 9 is a substantiallycentral vertical section through the lock shown in Fig. 7; Fig. 10

is a substantially horizontal section through the device shown in Fig.7; Fig. 11 is a fragmentary vertical cross section upon the broken lineindicated in Fig 9; and Fig. 12 is a detail showing in fragmentary forman inverted plan or bottom view of a bayonet slot used for accommodatingthe lock bolt.

Before proceeding to a more detailed explanation of my invention, itshould be clearly understood that the casing as well as the other partsof the lock, can be fashioned from any suitable material, and if sodesired, the casing of the lock can be ornamented in various ways.Preferably, the outside of the lock casing is rounded and entirelysmooth, so that it affords very little grip for the use of a tool, in anattempt to force the lock. The lock can be used with the ordinarystaples generally employed, which receive the bolt of a pad-lock, or itcan be used with specially formed eye-bolts which permit the lock casingto fit snugly against the door, and which are of just the proper size toreceive the bolt. The bolt itself, is extensible and has a sleeve which,when the key is inserted in the end of the bolt, is released and isresiliently projected from the casing so that the bolt itself can bewithdrawn from the staples to permit the lock to be opened. The end ofthe bolt when it is in an operative posit-ion within the casing, ispreferably flush with the outer surface of the casing.

Referring more particularly to the drawings, I provide a lock casing 10which is preferably in the form of a semiovoid, which is hollow and hasan opening 11 at the flat side to receive the staples or eye-bolts 12.At one end, the casing has therein a recess 13, and at the opposite endan opening 14, registering with the recess 13 and extending to theoutside of the casing. At one side, tl1e opening 14 has a cut-away part15 forming a shoulder 16, for a purpose which will appear more clearlyhereinafter.

In Figs. 1, 2 and 3 is shown the form of lock which is preferablyemployed with double doors A and A, each of which carries one of theeye-bolts 12. hen the lock is in position over the eye-bolts, the doorsare of course held together and are locked in a closed position, as willbe seen more clearly hereilr after.

The lock bolt 17 is substantially cylindrical and has one end 18 closed,the opposite end 19 being open to receive slidably a sleeve or extension20. The bolt is movably mounted in the opening 14; and in a closedposition has the end 18 seating in the recess 13 as is shown mostclearly in Fig. 2. The sleeve 20 has at one side, a slot 21 throughwhich projects the nose 22 of a dog 23 pivoted within the extension. Theend 2st of the dog remote from the nose 22, projects from the open,inner end of the sleeve and is engaged by a member 25 forced against thedog by av spring 26 located within the bolt and abutting against theclosed end of the same. The spring tends normally to force the dog intoa position such that the nose projects operatively from the slot 21 andthrough a registering slot 27 of the bolt. hen the dog is projected inthis way it is adapted to engage at the inner side of the shoulder 16 tolock the bolt in position. At the same time the sleeve 20 is in aretracted position within the bolt, the head 28 of the sleeve engagingat the open end 19 of the bolt.

The head 28 has the outer surface curved to conform to the curvature ofthe lock casing, so that when the bolt is within the easing, the surfaceof the lock is substantially smooth and unbroken, with the exception ofthe keyhole 29 formed in the end of the sleeve.

The bolt has a further slot 30 which receives a stud 31 carried by theextension sleeve, so that the movment of the latter with respect to thebolt is limited. A screw stud 32 extends inwardly of the casing, and isreceived by a slot of the bolt which constitutes a guideway, and limitsthe projection of the bolt from the lock.

The dog 23 has the inner edge so formed that a special type of key Balone, can be used to displace the dog into an inoperative position. Asis shown in Fig. %l, when the key B is introduced into the sleeve a partof the key engages a corresponding part of the dog to displace the same,so that the nose 22 can move into an inoperative position, the key beingsuitably cut away to permit this movement of the dog. Needless to say,dogs and keys of many different forms can be employed so that each keywill open one lock only. The key need not be turned; the thrusting ofthe key into the key-hole displaces the dog.

In the type of lock shown in Figs. 5 and 6 the casing is wedge-shapedand of sectoral cross section, so that it is adapted to fit snugly inthe angle formed by a door C and a part of the frame D. The casing 84:has sockets 35 therein, preferably connected with the casing by means ofintegral webs 36 and movably receiving the bolt 37. One of the socketshas an opening through the casing so that the bolt can be projected fromthe same as in the other form of the lock. The bolt 37 is similar inconstruction and mode of operation to the bolt 17.

In the form of my device shown in Figs.

7 to 12, inclusive, the double doors A, A and the staples 12 areidentical with those already described. The lock casing 88 is almostidentical with the lock casing 10. As may be seen from Figs. 7 and 12,the lock casing 38 is provided with a slot 2-39 having a widened portion10, being thus, because of its shape, a socalled bayonet slot. Slidablymounted within the lock casing 10 and staples 12 is a lock bolt 41 oftubular form, and mounted in one end of the latter is a spring l2.Disposed within the tubular lock bolt 4C1 and engaging the spring 42 isa cylindrical barrel A head at is provided for the cylindrical bolt 11and this head is provided with a. key-hole 15 which includes a slot etGextending upwardly, as indicated in Fig. 9. A stem 17 is connected withthe bottom of the barrel 18 and integral with this stem is a tlange -18.

Encircling the stem L7 is a band +19 serving as a guide. The stem 4C7 isprovided with slots 50, 51, 52, and slidably mounted within these slotsare tumblers 53, 51-, 55. These tumblers engage spiral springs 56, andfor this purpose are provided with pins 56 integral with the tumblersand extending through the spiral springs. Each pin 56" also extendsthrough the flange 18 which thus serves as a guide for the same.

The tumblers 58, 5'1, 55 are provided with outwardly extending portions57, 58, 58 serving as dogs or bolts. A leaf spring 59 is provided with aportion 59 which is secured to the stem 17. The leaf spring 59 isprovided with a dog (30 integral with it and serving the purpose of abolt which extends through a slot 61 in the barrel a3, and another slot62 in the lock bolt 11 A screw (33 extends into the lock casing 38 andprojects through a slot (3 1; in the lock bolt 41, so as to preventrotation of the lock bolt relatively to the lock casing and to serve asa guide for the latter. The barrel 4.3 is provided with a pin (36 whichextends outwardly through a slot (55 in the lock bolt 11, as will beunderstood from Fig. 8. This prevents the barrel $3 from turningrelatively to the lock bolt 1-1. The barrel 1; is

also provided with slots G7, (38, 09 having laterally extending portions67, GS, (39, the slots and their extending portions togetherconstituting so-called bayonet slots.

At 70 is shown the key which is separate from the lock and is of tubularform. This key is provided with a. dog 71 and with a guide 72 which fitsinto the portion {ill of the key-hole e5, as will be understood fromFig. 9. The key 70 is provided with slots 73, 74;, 75 of differentdepths for the purpose of receiving the tumblers 57, 58, 59, as will beunderstood from Figs. 9 and 10.

The operation of my device is as follows: Supposing that the parts arein their normal positions, as indicated in Fig. 7that is, the

doors are locked the tubular bolt 41 and parts associated therewith nowoccupy the positions indicated in this figure. In order to unlock thedoors, the operator inserts the key in the key-hole l5, the guide 72entering the portion 46 of the key-hole. The dog 71 now enters the slot61 occupying a position slightly to the left of the head 44:, as will beunderstood from Fig. 8.

The operator by exerting pressure upon the key causes first the bottomof the slot 73 (see Fig. 10) to engage the .tumbler 57; next the bottomof the slot (see Fig. 9) to engage the tumbler 55, and lastly the bottomof the slot 74 (Fig. 10) to engage the tumbler 54;. In doing this thetumblers, which are normally out of alinement with the laterallyextending portions 67, 68 69 of the slots 67, 68, 69, are brought intoalinement with these portions, the result being that the barrel 43 maynow be turned by the key. This being done, the bolt 60, which normallylodges in the portion 10 of the slot 39 (see Figs. 11 and 12) is turneda little, and no longer prevents the removal of the bolt 11 from thelock casing 88. Hence, the key 70, being turned slightly, the operatorpulls upon it and the lock bolt is withdrawn so that the doors may beopened.

Although I show my look as applied to doors, I do not limit myselfthereby for the reason that either form of the lock may be used inalmost any relation where a lock is desired for any purpose. Neither doI limit myself to the particular details of construction here set forth,as reasonable variations therein may be made without departing from thespirit of my invention.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent:
